Bob Metcalfe started working with computer networks in the 1970s and was part of Xerox's Palo Alto, Calif. team that invented what would become Ethernet, the foundational technology used to connect computers. He's known as "the father of Ethernet."
"I had never heard of Steve Jobs, and I had never heard of Apple, but and I had just started my own company so I turned him down," say Metcalfe, speaking to CNBC.
"And instead of getting angry with me, he helped me all all through the 1980s. My company benefited greatly from Steve's support, and he's one of my heroes."
